Batteries

Hello! I hope this is the correct section. Any how, I have been having some trouble figuring this out and I thought someone here could help me. My local Shopko has some cordless phone batteries on clearance for a great price. They are 3.6v NiMH, but I don't know how to charge them since I don't have a phone that uses that particular battery, but I have a phone that uses a slightly different 3.6v NiMH. The only difference is the mAh and the connector. Can I make an adapter for the connectors and use the phone to charge the battery? Or is that not a good idea? If it matters, the clearance one has less mAh.

Thanks for any help! E

Can I make an adapter for the connectors and use the phone to charge the battery

Yes, absolutely.

Great! They should make an awsome source of power.

The phone isn't accepting the battery for some reason. I think it might just be too old and dead. Would you, by chance, know any other ways of charging a 3.6v 800mAh NiMH battery? I have not been able to find any chargers that suit my needs.

Thanks! E

Obtain a sample from maxim-ic.com and make your own charger

I'd upgrade to Li batteries, charge circuits are much simpler see max1811 for example

Only drawback is dealing with surface mount parts. Takes a good eye steady hand, and solder flux.
